SPECIFICATION forming part of Letters Patent No. 693,371, dated February 18, 1902.

v Application iiled July 16,1901.

To all whom, it Trtnty concern:

Be it known that'I, DAvID BUTLER, a citizen of the United States, residing at Border City, Seneca county, New York, have invented certain new and useful Improvements in Window-Balconies, of which the following is a specification.

My invention relates to improvements in window-balconies foruse in the windows of buildings; and the objects of my improvement are to provide, first, a safe reliable window- -balcony for the use of janitors or workmen desiring to work on the `outside of the Windows of a building, and, second, a Window-balcony so constructed that it may be quickly and conveniently placed in position for use in a Window without being attached to the building by means of screws or other devices and quickly and conveniently folded up and removed when the Work has been performed. I attain these Objects by the mechanism illustrated in the accompanying drawings, in whichf Figure l is a perspective view of my balcony when placed in position in the window Fig. 2 is a sectional view of the balcony in the same position. Fig. 3 is a View of the balcony removed from the window and partially folded. Fig.

4 is a detail of the angle-bars of the balcony upon Which the platform rests and the lock which catches on the inside of the windowsill when the balcony is in position. Fig. 5 is a view of the end of Fig. 4, showing the end of one of the angle-bars and a rear view of the lock. Fig. 6 is a side detail of the lock. Fig. 7 is a front detail of the lock.

Similar letters refer to similar parts throughout the several views.

In Fig. 1, s s are angle-shaped steel bars resting on the window-sill in a horizontal position, extending outwardly parallel to each other and at right angles to the window-sill, with the angle so adjusted that the ends of the boards m 'm fm. rest in the angles of thesebars. n n are round iron braces made of gas-pipe, resting with the foot against the wall of the building and furnishing support to the outer ends of the bars s s at d d.

o o, it, o fu, and w are iron bars each one inch in width and one-eighth of an inch in thickness and together constitute a frame to Serial No. 68,552. (No model protect a person from falling from the balcony. i x

q, z, andp are connecting rods or slats connecting the bars s s. f

trepresents an ordinary construction of rulejoint.

When the balcony is in position as shown in Fig. 2, the steel bars s s are supported at their outer extremity by the braces 'n n and are kept from slipping outward by the lock m'. The manner of the attachment of thel lock o0 is shown by Fig. 4E. A z' and j are steel bolts extending through the lock m, as shown in Fig. 7. Along the top of the bars s s, near the inner end, are small notches, one of which is marked lo, as shown in Fig. 4.. When the balcony is-placed in position in a Window, the bolt't is placed lin one of these notches. The balconycan be adj usted to any thickness of wall in a building by sliding the lock a: backward or forward on the bar s.

When the balcony is in position and weight is put upon the ioor m m m, the adjustable lock .fr will be drawn tightly against the inside of the Window-sill, as shown in Fig. 2. Pressure on the inside of the lock o: by the -window-sill at l, as shown in Fig. 2, will result in holding the bolt 1.' downinto the notch 2c Vwith greater firmness, so that the greater the pressure on the platform m m fm the more firmly is the balcony held'at Z by the lock cc.

The frame of the balcony is so constructed` 85 `removed from the window.. At b, c, d, c, and v that it can be folded as shown in Fig. 3 when g the bars of the frame are fastened together by rivets, headed at 'each end, upon which rivets the bars turny at the points named. When the balcony is in position in a window and it is desired; to remove it, a person standing inside the window may take hold of the frame at o c, and drawing it toward him lthe balcony folds into the position shown in Fig. 3;

Having thus described my invention, what I claim as new, and desire tosecure byrLetters Patent, is r l. In a portable window-balcony, a Hoorframe, a guard-frame pivoted tothe outer end of said floor-frame, a brace pivoted under said IOO floor-frame, and means pivoted to said iio0r.-

frame to cause the free ends of said guardframe and said braces to simultaneously swing toward each other, substantially as shown and described.

2. In a portable window-balcony, the side rods of the floor-frame interior of the window notched correspondingly, a lock consisting of a U -shaped piece of metal having a bolt therethrough adapted to seat in said notches, a bolt adapted to press against the bottom of the side rod, and a wedge-shaped piece secured in said U-shaped piece, substantially as shown and described.

3. In a portable window-balcony, a frame constructed to support a door, and adapted to project through a window, braces extending downwardly pivoted to the outer part of the frame, a guard-frame pivoted to the front of said floor-frame, a lever pivoted on each side of said floor-frame, an arm connecting each lever with the brace on the corresponding side of the floor-frame, an arm connecting the lever with the guard-frame, and means to prevent said frame from slipping outwardly, substantially as shown and described.

4C. In a portable window-balcony, a floorfrarne having side rods made of angle-iron to support the floor of the balcony,a guard-frame pivoted to the outer end of said floor-frame, a brace pivoted to each side rod, a lever pivoted to each side rod, an arm connecting the upper end of each lever with the guard-frame, an arm connecting the lower end of the lever with the brace, the inner end of each side rod notched ou its upper edge, and a lock adapted to seat in said notches to prevent said balcony slipping outwardly, substantially as shown and described.

5. In a portable window-balcony, a frame having side rods made of angle-iron to support floor-boards and adapted to project through a window, a brace pivoted to each side rod and swinging downwardly, a guard-frame pivoted to the front of said frame, a lever pivoted on each side of said door-frame, an arm connecting each lever with the brace on the correspondingside oi' said floor-frame, an arm connecting the lever with the guard-frame, notches on the Hoor-frame, and locks adapted to bear in said notches to prevent outward slipping of the balcony consisting of U -shaped pieces of metal carrying bolts to impinge in said notches and against the bottoni of each side rod, and a wedge-shaped piece ixedly secured between the arms of said U-shaped G.
